英文摘要	We develop an n-coordination strategy to design a robust co2 reduction reaction (co2rr) electrocatalyst with atomically dispersed co-n-5 site anchored on polymer-derived hollow n-doped porous carbon spheres. our catalyst exhibits high selectivity for co2rr with co faradaic efficiency (feco) above 90% over a wide potential range from -0.57 to -0.88 v (the feco exceeded 99% at -0.73 and -0.79 v). the co current density and feco remained nearly unchanged after electrolyzing 10 h, revealing remarkable stability. experiments and density functional theory calculations demonstrate single-atom co-n-5 site is the dominating active center simultaneously for co2 activation, the rapid formation of key intermediate cooh* as well as the desorption of co.
